What is wishlist?
Wishlist is a section or a compartment of your account where you can add products to it by clicking on the heart shape wishlist icon on the product page or on the product listing page over product image.
When you like any product but you would like to check out this same product later some day and do not want to search for it on the whole website, you can add this product to wishlist so that you can find it there right away without going into the hassle of searching the huge catalog of products. Access your Wishlist.
